This document discusses various types of man-made and natural disasters. It describes the Chernobyl nuclear disaster where a reactor failed in 1986, releasing radiation that will impact the area for 70 years. It also details the Bhopal gas tragedy in India in 1984 when a chemical plant leaked methyl isocynate gas, exposing over 50,000 people. The document outlines how human activities can exacerbate natural disasters like droughts, landslides and floods, creating "hybrid" disasters. It stresses the importance of disaster management in India and the roles of government agencies and remote sensing satellites in monitoring and responding to disasters.

1. Man-made disasters

2. Man-made disasters
Man made disasters include rail-road
accidents, bomb blasts, leakage of
chemicals, fires, communal roits,
terrorist attacks and nuclear accidents
which originate from human planning
errors or negligence.

3. Chernobyl disaster on 29th April
1986
It happened because of a
melt down in a reactor. The
reactor failed and
radioactive rays were
released into atmosphere.
It is believed that the
impact of the radiation
would be for another 70
years.

4. The Bhopal gas Tragedy
It is considered the worst
industrial chemical
disaster that happened
due to the leakage of
poisonous gas.
Over 50,000 people were
exposed to Methyl
isocynate gas and other
chemicals.

5. Hybrid disasters
Human beings have
interacted with natural
environment to such an
extent that their
activities have had
disastrous consequences
for human beings
themselves.
Drought
Landslides
Famine and crop
failure
Chemical poisoning
Earthquake
Hurricane and
cyclone

6. Fire hazards
1. Smoke
detectors
2. Fire prevention
strategy
3. Family fire
drills

8. Disaster management in India
Moving the injured and
affected to safe shelters.
Providing immediate first
aid to the victims.
Providing food and safe
drinking water and shelter.
Provide financial help for
fast recovery.

9. Role of the government
The government of India along with United
Nations Development Program (UNDP) has
formulated a disaster risk management
programme that emphasizes on creating
awareness.
The National disaster management (NDM)
involves in training of engineers, architects and
masons in safe construction practices.

10. Role of remote sensing satellites in
natural disasters
To monitor the disasters
To keep track of a flood
To detect burning fires
To alert about the pollution
level in coastal areas
To check desertification
with the help of satellite
images.

11. Homework
1. Describe about Bhopal gas tragedy.
2. What is NDM? What are its objectives?
3. How are remote sensing satellites helpful in
detecting a natural disaster.
4. Explain hybrid disaster with examples.
